# Tibetan OCR — Stok
<!-- DRAFT. Open-access subset of the OPTranskribus alignment set. Numbers measured 2026-08-18. -->
**806 page images of Tibetan Kangyur manuscripts (uchen) with page-level Unicode
transcriptions.** The transcriptions were produced by **[OpenPecha](https://openpecha.org/)**
with the [Transkribus](https://www.transkribus.org/) handwritten-text-recognition
platform over **BDRC** manuscript scans of the **Stog Palace Kangyur** (`MW22083`)
Used in the **BDRC Tibetan OCR** effort; see the model
[`BDRC/tibetan-ocr`](https://huggingface.co/BDRC/tibetan-ocr) and the
[evaluation benchmark](https://huggingface.co/datasets/BDRC/tibetan-ocr-benchmark).
